The alternator runs the majority of the time between 1,800 and 4,200 rpm, which corresponds to the vehicle idling and at cruising speed. The most problematic situation occurs with the vehicle stationary and the engine idling: the battery has its maximum current draw and the alternator is generating its minimum current output. Under the worst-case conditions, corresponding to engine idle speed (for example in a traffic jam), the FPT genuine alternator produces up to 30% more current than competitors. This ensures a reliable engine power supply system.

FPT genuine alternator can provide you with high and constant performance under any conditions, providing the necessary charge and keeping your battery in good health even in the long term.

Periodically check that the electrical contacts of the alternator are clean and firmly fastened. With the engine running, pay attention to any noises or vibration coming from the alternator, obviously first and foremost paying attention to traffic laws and personal safety requirements; in the event of any unusual noises or stresses, check that the serpentine belt is at the correct tension and replace if worn. When changing the serpentine belt, check that the alternator pulley is firmly attached and does not exhibit excessive clearance; replace the alternator with an original FPT spare part in the event of abnormal pulley movement.
